Is the EPDS a magic wand?: 2. 'Myths' and the evidence base

Research has shown that the Edinburgh Postnatal Depression Scale (EPDS) is a valid screening tool and that health visitor interventions based on non-directive counselling are effective treatments for postnatal depression. Purchasers and managers are therefore requiring health visitors to use the EPDS. The result should be good evidence-based practice. Research on the EPDS and associated health visitor interventions has actually been interpreted very differently in different areas. Worrying misunderstandings have arisen. Implicit and explicit assumptions in some current systems have been examined in the light of available evidence. Where no research has been reported evaluation has been based on experience in health visitor training and clinical practice. It is concluded that the development of good evidence-based practice requires critical appraisal of research. New ways of working require a carefully planned collaborative approach between appropriate health care professionals and service users. Training and ongoing support are crucial when new practices are introduced.
